Aluminized Enhanced Blast Explosive Based on Polysiloxane Binder
Propellants, Explosives, Pyrotechnics, Volume 47, Issue 2, February 2022., 2022 Abstract Drastic measures are taken in order to improve the properties of enhanced blast explosives. First, a binder with high reactivity as reducing agent is selected. The binder, platinum cure silicone, generates pyrophoric decomposition products in situ during the detonation.

Metallographic Investigation on Postweld Heat‐Treated0.21%C‐1020 Steel Plates Joined by SMAW Method
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 This paper presents analysis and comparison into mechanical behaviour and microstructural attributes of postweld heat‐treated AISI 1020 (0.21%‐C) plates joined by the shielded metal arc welding (SMAW) process. The purpose of this work is to heat the welded samples uniformly so that a possible formation of austenite can be obtained, and hence, residual ...

Mechanistic study of the carbonated smart water in carbonate reservoirs
Greenhouse Gases: Science and Technology, Volume 11, Issue 4, Page 661-681, August 2021., 2021 Abstract Carbonated smart water (CSMW) injection has drawn considerable interest, especially in the last decade. This interest stems from its results in the recovery factor enhancement and the storage of carbon dioxide. This method has been mainly studied for sandstone formations, and less devotion has been given to carbonates, especially in naturally ...

Materials and Corrosion, Volume 72, Issue 3, Page 504-516, March 2021., 2021 Weld metal consisting of different steel phases was created by underwater wet shielded metal arc welding. Samples based on ISO 3690 were welded with one, two, or three weld seams of different electrode grades. The diffusible hydrogen content of these welds was analyzed. Over 90% reduction of diffusible hydrogen could be achieved.
